Editing Preon (section)

==Goals of preon models==
Preon research is motivated by the desire to:
* Reduce the large number of particles, many that differ only in charge, to a smaller number of more fundamental particles. For example, the [[down quark]] and [[up quark]] are nearly identical except for charge, and a slight mass difference; preon research is motivated by explaining that quarks are composed of similar preons, with incremental differences accounting for charge. The hope is to reproduce the [[reductionist]] strategy that has worked for the [[periodic table of elements]] and the [[quark model]] of mesons and baryons.
* Explain the reason for there being exactly three [[Generation (particle physics)|generation]]s of [[fermions]].
* Calculate parameters that are currently unexplained by the Standard Model, such as the [[mass]]es of S.M. fundamental fermions, their [[electric charge]]s, and [[color charge]]s; in effect, reduce the number of model-required experimental input parameters from the number required by the Standard Model.
* Provide reasons for the very large range of mass-energy observed in supposedly fundamental particles, from the [[electron neutrino]] to the [[top quark]].
* Provide alternative explanations for the [[electro-weak]] [[symmetry breaking]] without invoking a [[Higgs field]], which itself possibly needs a [[supersymmetry]] to correct the theoretical problems involved with the Higgs field;{{which|date=February 2016}} (further, the supersymmetric theories proposed so far have theoretical and observational problems of their own{{which|date=February 2016}}).
* Account for [[neutrino oscillation]] and apparently [[neutrino#neutrino_mass_anchor|unique mass mechanism]].
* Make new, non-repetitive predictions, such as providing [[cold dark matter]] candidates.
* Explain why there exists only the observed variety of particle species, and give a model with reasons for producing ''only'' these observed particles (since the prediction of non-observed particles is a problem with many current models, such as [[supersymmetry]]).
